'DRAFT-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 316,552, dated April 28, 1885 Application filed February 6, 1884. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. LoRE, of Fayette, in the county of Seneca and State of New York, have invented a new and Improved Draft-Regulator, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved draft-regulator for stovepipes, which regulator also serves as a ventiro lator.

The invention consists in certain improvements in that class-of draft-regulators formed of two hollow truncated cone-sections united at the base edges, and having the truncated I5 ends coupled to the stove-pipe, the bottom conesection having a series of apertures which can be closed by a valve-plate resting on the inner surface of the bottom cone-section,as will be hereinafter fully described and claimed.

r In these draft-regulators above referred to, in one instance a pipe carrying a damper passed entirely through the sections of the ventilator and had oblong apertures communicating with the chamber formed by the cone 2 5 sections, and around the outside of this chamber the cone-shaped valve-plate was situated. In another instance the pipe carried. a dampv er and projected above the cone-shaped valveplate, but not into the pipe above it.

The damper and valve were connected in the above construction, and were simultaneously operated to alternately open and close. In another instance the valve-plate was formed W-shaped in cross-section, openings in the two middle arms registering with the stovepipe, and openings in the outer arms registering with openings in the outward-flared end 'of the pipe and communicating with the outor air. In these several constructions soot in 40 falling down the pipes would collect between the pipe and draft-regulating plate and between the outer and middle arms of the draft regulating plate, so that every time the'dratt regulating valve-plate was operated the soot would fall into the room and upon the stove and carpeting. By my construction these disadvantages are obviated and at the same time the cost of manufacture is lessened.

Reference is to be had to the accompanying 5o drawings, forming part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side View of my improved draft-regulator, showing it held on a stovepipe. Fig. 2 is an enlarged side view of the draft regulator. Fig. 3 is a sectional plan View of the same on the line a: :0, Fig. 2.

A casing, A, is formed of hollow truncated cones A A, united at the base, the casing be ing connected at the truncated ends of the cones with the stove-pipe B; but the stovepipe does not projectinto the cones, and here is a very essential feature of my invention. The stove-pipe ends at the truncated ends of the cones, so that there is no obstruction 6 5 throughout the pipe and valve-casing. There are no plates for the soot to accumulate on and fall into the room when the valve-plate is operated. The bottom cone-part, A is provided with a series of apertures, G, which can be closed by a conical valve plate, D, fitting closely on the inner surface of the bottom cone part or section, A which valve is provided with as many recesses or openings E as there are apertures O in the bottom cone-section, A The valve-plate D is provided with a handle-lug, F, projecting out of one of the apertures G in the bottom cone-section, A The valve-plate D rests loosely on the inner surface of the bottom section, and is not held on the same by any clips, lugs, &c., which might become clogged by the soot, dust, &c. The regulator is arranged some distance above the stove, so that a draft will be created in that part of the pipe below the regulator, and the smoke, 850., will have a strong upward movement at the regulator. The apertures G can be opened more or less by means of the valve, according to the draft required, the draft increasing as the apertures are closed. The 0 regulator also prevents condensation of the smoke. The regulator is also a good ventilator, which carries off the foul air in the room very rapidly.

Having thus described my invention, what 5 I claim as new, and desire to secure by Letters Patent, is-

A draft-regulator consisting of a casing formed of two truncated hollow cone-sections united at their bases and having their trunc- ICO ated ends connected with the ends of the pipes, I plate resting on the inner surface oi the botsaid pipes extendinginto the cone-sections tom section, A, and provided with apertures only a sufficient distance to unite them with E, wherebya draft-regulator is'provided havsaid sections, the bottom conesectiou being ing an unobstructed interior surface to pre- 15 5 provided with a series of apertures which can vent the collection of dust and soot, substanb; closeddby avalve, substantially as herein tially asherein shown and described. s own an described.
